## What the aircraft actually flies over

From London the path crosses United Kingdom, then Ireland, then 6,433 km of open water.

The furthest the great circle gets from the equator is 52.1°N, 12% of the way along.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 7,375 km. That is 266 km further, about 4% more, and roughly 20m of extra flying.

Leaving London the aircraft points west (279°); it arrives into Miami heading south-west (223°). That is 56° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.

One economy seat on it is about 1.01 t of CO₂e each way, counting non-CO₂ warming.
